Best Way to Handle JSON response in Laravel

Question

I use Laravel 5.5 and PHP 7, and I'm creating a form like this.

<form id="form" name="xxx" action="post">
  <input type="text" name="body_color[1][en]">
  <button type="submit" name="submit">Submit</button>
</form>

I post data via Ajax, and I receive the following response from Laravel when I have an error.

error: body_color.1.en: ["The body color.1.en field is required."] success: false

If Laravel doesn't replace "[" and "]" with a dot, I can show an error message on the browser efficiently using jQuery.

$('#form *[name=body_color[1][en]]').after('input error!');

How can I show a simple error message in the web browser?

With your jQuery requirement, a simple regex replacement should work for this case:

var str = "body_color.1.en"
str.replace(/\.(.+)\./, "[$1][") + "]" // returns body_color[1][en]

Or you could just split the string on the dots and rebuild it:

str.split('.')  // returns ['body_color', '1', 'en'];

There are many existing Javascript classes out there to handle the error responses, ex: https://github.com/spatie/form-backend-validation

run your response through JSON.parse(response) and you should be able to use standard json dot syntax to step through the data.

var r = JSON.parse(response):

console.log(r);
